Actually, no, at least not with my tests; it appears to crash as a result of this change between the last build that didn't crash and the first build that did:

Index: ui/gtk/main_statusbar.c

     packets_bar_update();

 }
 
If I remove those four lines, it doesn't crash - and if I put back the status_capture_comment_hide() call, it still doesn't crash, so it's the status_expert_hide() that ultimately causes the crash.

The widgets that status_expert_hide() hides are event boxes, which, according to the documentation:

	http://developer.gnome.org/gtk3/stable/GtkEventBox.html

have their own windows.  Perhaps this is an issue with the Windows version of GTK+?

(No, I don't know why that only happens with "-k".  Adding null pointer checks in status_expert_hide() doesn't fix the problem, but perhaps adding "-k" means that those widgets have been created, but *not* yet properly initialized, by the time status_expert_hide() is called?)
